Re: Strange Grant behavior in postgres 8.3

Sorry for some confusion. I re-created the whole thing again with
fresh users and a fresh database:

(1) Create a new user and a new db, also create a table 'test' inside
with user 'foo'

$> createuser -U postgres -P -E foo
$> createdb -U postgres -O foo -E utf8 foo_test

(2) create a second user

$> createuser -U postgres -P -E bar

just a check for db ownership

=> \l
               List of databases
         Name         |    Owner     | Encoding
----------------------+--------------+----------
 foo_test             | foo          | UTF8

(3) check the database rights (with user postgres)
# select * from pg_database where datname = 'foo_test';
 datname  | datdba | encoding | datistemplate | datallowconn |
datconnlimit | datlastsysoid | datfrozenxid | dattablespace |
datconfig | datacl

----------+--------+----------+---------------+--------------+--------------+---------------+--------------+---------------+-----------+--------
 foo_test |  72427 |        6 | f             | t            |
  -1 |         11510 |          379 |          1663 |           |
(1 row)

(4) login as user bar and get correct error

=> select * from test;
ERROR:  permission denied for relation test;

(5) give user 'bar' full rights to the database 'foo_test' as logged
in with user 'postgres'

# grant all on database foo_test to bar;

(6) check rights again

datname  | datdba | encoding | datistemplate | datallowconn |
datconnlimit | datlastsysoid | datfrozenxid | dattablespace |
datconfig |              datacl

----------+--------+----------+---------------+--------------+--------------+---------------+--------------+---------------+-----------+-----------------------------------
 foo_test |  72427 |        6 | f             | t            |
  -1 |         11510 |          379 |          1663 |           |
{=Tc/foo,foo=CTc/foo,bar=CTc/foo}

(7) login again with 'bar' user

=> select * from test;
ERROR:  permission denied for relation test

still cannot select

rights for the table inside (the same for postgres, foo or bar user):

# \z
 Access privileges for database "foo_test"
 Schema | Name | Type  | Access privileges
--------+------+-------+-------------------
 public | test | table |

So what do I do wrong? Even if I do the GRANT command as user 'foo'
who is the database owner, I still cannot select with the user 'bar'.
It only works if I set GRANT rights for the TABLE itself:

as user 'foo' logged in
=> grant all on table test to bar;

=> \z
 Access privileges for database "foo_test"
 Schema | Name | Type  | Access privileges
--------+------+-------+-------------------
 public | test | table | {foo=arwdxt/foo,bar=arwdxt/foo}

and then login again with user 'bar'

=> select * from test;
 test
------
 foo
(1 row)


I am seriously confused and ask myself what I do wrong
